Dry, light and clean system, compact (less than 5 cm thick), ideal for rehabilitation and occupied premises, Optima Sonic improves acoustic performance for existing walls and partitions. Knowing that the acoustic insulation of the ceilings is complementary to obtain a high-performance result, the Optima Sonic system has been adapted to them and described in the sheet: "low-thickness acoustic insulation for ceilings".

Principle of thin sound insulation
Reinforce sound insulation of party walls in apartment or semi-detached house
In the room or rooms concerned, the ideal is to isolate not only the walls but also the ceiling by losing the minimum of living space. Indeed, the transmission of noise is effected by the separative but also lateral walls. It is therefore necessary to identify the wall or walls carrying the noise. It will sometimes be necessary to have a diagnosis made by an acoustic specialist.
The Optima Sonic system is a thin solution (less than 5 cm finished, with a 28 mm insulation only). It is adjustable in thickness and ensures a good acoustic performance. It can handle impact and overhead noise. In addition, it allows the passage of electrical ducts without degradation of the acoustic performance.
Isolate parts to reduce interior noise
In a dwelling the reinforcement of the acoustic insulation of the partition walls (between living rooms) also improves the comfort. Optima Sonic is recommended to reduce indoor airborne noise (TV, radio, voice) that spreads mainly through the wall separating two rooms.
Airborne noise is accompanied by indirect transmissions (passage of noise through the sidewalls). For a good comfort, the noise level perceived in a room must be lower than 30 dB.
Implementation of thin sound insulation
1. In the wall... Start by attaching the Clip'Optima rails at the top and bottom of the wall to ensure perfect alignment. Fix in the wall, every 60 cm in width, the intermediate supports (spacer PL 25, 35 or 45 mm) according to the desired thickness, to 130 cm of maximum maximum.
2. Seam the Soniroll glass wool strips through the spacers. Screw the rosettes to maintain the insulation.
3. Clip the metal furring on the rosettes after inserting them into the Clip'Optima rails. Integrate the electrical ducts if necessary.
Lay the siding on the furs and screw every 30 cm: plasterboard BA 13, BA 15, BA 18 or Hydro plates or high hardness.
